Nuclear power produces almost a fifth of the world's electricity. Supporters say it's safe, cheap and - best of all - the answer to global warming. Critics say it's not safe, or cheap. And it won't really help with the global warming problem. So who's right? This program presents the arguments for and against, with relevant background information. Issues covered in this program include: radioactive waste: how hazardous is it?; Can it be safely stored?; How likely is an accident at a nuclear power plant?; What could the consequences be?; Are nuclear power stations terrorist targets?; Does nuclear power encourage the development of nuclear weapons?; Is nuclear energy carbon-free'?; Is it the solution to global warming?
